Bio-geographical regions - Annex 3

Although the circumpolar countries endeavor to support monitoring programs that provide good coverage of Arctic and subarctic regions, this ideal is constrained by the high costs associated with repeated sampling of a large set of lakes and rivers in areas that often are very remote. Consequently, freshwater monitoring has sparse, spatial coverage in large parts of the Arctic, with only Fennoscandia and Iceland having extensive monitoring coverage of lakes and streams Figure 6-2 Current state of monitoring for river FECs in each Arctic country State of the Arctic Freshwater Biodiversity Report - Chapter 6 - Page 94 - Figure 6-2

This dataset was compiled to describe the intertidal meiobenthic community of Kongsfjorden and to better understand the relationship between the horizontal and vertical distribution of meiofauna with a special focus on nematodes and environmental features

<p>The study of long-distance migration provides insights into the habits and performance of organisms at the limit of their physical abilities. The Arctic tern Sterna paradisaea is the epitome of such behavior; despite its small size (-lt;125 g), banding recoveries and at-sea surveys suggest that its annual migration from boreal and high Arctic breeding grounds to the Southern Ocean may be the longest seasonal movement of any animal. Our tracking of 11 Arctic terns fitted with miniature (1.4 g) geolocators revealed that these birds do indeed travel huge distances (more than 80,000 km annually for some individuals). As well as confirming the location of the main wintering region, we also identified a previously unknown oceanic stopover area in the North Atlantic used by birds from at least two breeding populations (from Greenland and Iceland). Although birds from the same colony took one of two alternative southbound migration routes following the African or South American coast, all returned on a broadly similar, sigmoidal trajectory, crossing from east to west in the Atlantic in the region of the equatorial Intertropical Convergence Zone. Arctic terns clearly target regions of high marine productivity both as stopover and wintering areas, and exploit prevailing global wind systems to reduce flight costs on long-distance commutes.-nbsp;</p>

This dataset contains Amphipod distribution records and is based on literature from the years 1931 to 2018. The data were collected during a variety of cruises and sampling events while the majority was obtained during the Danish Ingolf expedition. Sampling events took place in the North Atlantic and Arctic waters which included the Artic Ocean, Barents Sea, Kara Sea, Labrador Sea, Buffin Bay and Greenland Sea. Amphipods were predominantly collected using dredges, epibenthic sledges and remotely operated vehicles but scuba divers and vehicle-free baited traps were also used. This way, over 1566 Amphipod samples were collected in total which include 45 families, 117 genera and 164 species.

HERMES data in PANGAEA only include meiobenthos abundances at the Arctic Håkon Mosby Mud Volcano (1037 records) and meiobenthos abundances in the Black Sea during Poseidon cruise.
